American Petroleum Institute gravity is a term often used to measure how heavy or light a petroleum liquid is comparing to waterCalculating the API gravity from Liquid density or specific gravity or preloaded database of fluids.Calculate the specific gravity from API gravityCalculate the Barrels of crude oil per metric ton from API Gravity or select a fluid from the preloaded fluids database to perform the calculationFind the classification of oil according to API gravity (Light oil, Medium oil, Heavy oil or Extra heavy oil)

Used for Fluid flow in centrifugal pump. The calculator can also calculate the pump head providing that the Cavitation coefficient is defined

Dimensionless number used in flow calculations analysis. the number reflects the relationship between the difference of a local pressure from the vapor pressure and the kinetic energy per volume, Cavitation number is used to characterize the potential of the flow to cavitate.Calculate the Cavitation NumberBack calculate the local Pressure or Fluid vapor Pressure or Fluid velocity

Use API RP 14E to estimate the erosional velocity, the calculator will calculate the following:Mixture DensityErosional velocityMinimum pipe cross sectional area

Calculate the head loss and pipe cross sectional area using Darcy Weisbach equation also plot profile charts of pipe cross sectional area versus head loss and velocity versus head loss

Calculate any unknown one or two temperatures on the hot side or the cold side.
